Or for poor people without electricity? Either way what a work out especially if you are a porn dog! :D
Ooops that leaves out the DUmp! :DSustainable Working Human Power as you use the XO!
Just this morning we tested the first prototype - the PAIWASTOON team that perform the technical implementation designed a new pedal powered machine that can power the XO as you pedal and use it at the same time. Even small kids (3/4th grade) can power it.
Behold the future! HAha, going green!
